After testing, my initial thoughts appeared to have been correct. I had
to modify the patch as follows. To test, simply do:
truncate -s 10m img
losetup /dev/loop0 img
parted /dev/loop0
mklabel msdos
mkpart primary ext2 1m 2m
quit
ls /dev/loop0*
Note the /dev/loop0p1 node. Run losetup -d /dev/loop0 and see if it is
still there.
